Not surprizingly, being 'smart' comes at a price of added complexity. This is
text.
To provide a solution for both cases, wxWindows has two predefined classes

\helpref{wxDataObjectSimple}{wxdataobjectsimple} is
the simplest wxDataObject possible and only holds data in a single format (such
as HTML or text) and \helpref{wxDataObjectComposite}{wxdataobjectcomposite} is
Please note that the easiest way to use drag and drop and the clipboard with
multiple formats is by using wxDataObjectComposite, but it is not the most
efficient one as each wxDataObjectSimple would contain the whole data in its

your proprietary format, as well as Word, RTF, HTML, Unicode and plain text to
the clipboard and even today's computers are in trouble. For this case, you
will have to derive from wxDataObject directly and make it enumerate its
formats and provide the data in the requested format on demand.
Note that neither the GTK data transfer mechanisms for the clipboard and

actually requests the data. This is in contrast to the 'feel' offered to the
user of a program who would normally think that the data resides in the
clipboard after having pressed 'Copy' - in reality it is only declared to be
available.
There are several predefined data object classes derived from

-\helpref{wxTextDataObject}{wxtextdataobject} and

"application/word" or "image/png". These strings are used as they are under
Unix (so far only GTK) to identify a format and are translated into their

translation under Windows is not yet finished.

of its functions which are pure virtual in the base class.
